Kristen Stewart raised eyebrows when she was spotted wearing Robert Pattinson’s T-shirt as she headed out from LAX on Wednesday.

Her estranged ex was wearing the same IRIE shirt in July last year while walking his dog Bear.

While the “Twilight” star gave no further tidbits as to why she donned her jilted lover’s old shirt, perhaps Urban Dictionary’s definition of the word “IRIE” suggests what KStew wanted to tell her fans.

“The way you feel when you have no worries – to be at total peace with your current state of being.”

The “On the Road” actress is set to make her first red carpet appearance at the Toronto Film Festival since her dalliance with director Rupert Sanders.
